    Abstract: Provided is an inter prediction method including determining a collocated block of a current block of a current image from among blocks of an image that is restored prior to the current image; preferentially checking whether a first reference list from among reference lists of the collocated block is referred to and selectively checking whether a second reference list is referred to according to whether the first reference list is referred to; based on a result of the checking, determining a single collocated reference list from among the first reference list and the second reference list; determining a reference block of the current block by using motion information of the collocated reference list; and performing inter prediction on the current block by using the determined reference block.

    Abstract: An apparatus for decoding an image, the apparatus including an entropy decoder that performs entropy-decoding to obtain quantized transformation coefficients of at least one transformation unit in a coding unit of the image, a decoder that determines a prediction mode of at least one prediction unit in the coding unit from information indicating the prediction mode for the at least one prediction unit, when the prediction mode is determined to be an inter prediction mode, not in an intra prediction mode, determines a size of the at least one transformation unit in the coding unit regardless of a size of the at least one prediction unit in the coding unit, and performs inverse-quantization and inverse-transformation on the quantized transformation coefficients of the at least one transformation unit to obtain residuals, and a restorer that performs inter prediction for at least one prediction unit in the coding unit to generate a predictor and restores the image by using the residuals and the predictor.
